intel_extreme: Improve accelerant tracing and debug output

* Several messages to syslog weren't tagged with
intel_extreme making troubleshooting difficult
* Fix a few typesize printf issues with B_PRI macro

intel_extreme: Add IvyBridge fixups

* Add initial clock gating fix (may need tweaking)

The display line length constraint is different on <= G35 cards.
* Decide which constraint to use depending on the card model.
* May fix #8001, only tested on my hardware which already worked...

Add workaround for #8001.
* check known mode list first before sanitizing the target mode. However the optimal way is to fix the constraints in sanitize_display_mode.

Use timing constraints from the G35 programming manual (which are much more relaxed)
Should help with #8001.

* Add a couple more SandyBridge IDs. They might work, but I can't test them.
* Also add the definitions and some specifics for IronLake (ILK), but keep the
IDs disabled as at least the one version I can test with doesn't work yet.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@42869 a95241bf-73f2-0310-859d-f6bbb57e9c96

Style cleanups only, no functional change.
* Make the pointer style consistent accross all components, which should make it
easier when working all over the place.
* 80 char limits.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@42863 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Rework how registers are accessed. Most registers are now grouped into
register blocks and we encode their block into the register definition. On
register access these blocks are then translated into the final address.
* Set up the register blocks for (G)MCH and PCH variants.
* Remove most SandyBridge code that was actually PCH specific and is now taken
care of automatically.
* This will temporarily break SandyBridge support again until the right
transcoders are actually programmed.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@42857 a95241bf-73f2-0310-859d-f6bbb57e9c96

Add indexed color mode support for SandyBridge.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@42851 a95241bf-73f2-0310-859d-f6bbb57e9c96

Apply r42844 to the analog case as well.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@42845 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Use the actual (virtual) width and height instead of the display timing
values, as those might be slightly off (when coming from the GTF for example)
and cause needless display scaling.
* Tiny cleanup.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@42844 a95241bf-73f2-0310-859d-f6bbb57e9c96

Fix comparison.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@42843 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Add preliminary support for one SandyBridge mobile integrated graphics device
(the one in my new ThinkPad X1). The PLL is still off a bit so it has a few
blurry stripes, but EDID and mode setting basically works.
* Starting with IronLake the north/south bridge or (G)MCH/ICH setup was moved
into a platform control hub (PCH) which means that many registers previously
located in the GMCH are now in the PCH and have a new address.
* I'm committing this mostly because this way the additions are more easy to
follow. It is a bit messy and I'll clean it up more and possibly make it a
bit more generic. Also most of these changes actually apply to IronLake and up
and aren't SandyBridge specific, so a few of those additions will still get a
broader scope and new chips will be added.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@42839 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Implemented intel_propose_display_mode() using the new helper functions.
* In intel_set_display_mode(), we now use the sanitize_display_mode() method
directly in order to see if the mode is valid (it's valid when it doesn't
need to be altered anymore).
* This should be the final nail on ticket #7419.
* Automatic whitespace cleanup.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@42742 a95241bf-73f2-0310-859d-f6bbb57e9c96

Always set the palette registers even if the head is not connected. This will not do anything bad (if the display is disabled, it has no
effect), and since the test was a bit too constraining (I have an LVDS panel on head A), it would prevent setting colors for the CMAP modes.

This finally gets the \n demo working from the original binary from BeOS, without any change.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@42523 a95241bf-73f2-0310-859d-f6bbb57e9c96

* added support for the Atom IGD, based on the X driver sources (fixes #6202)
* fixes G4x PLL limits


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@40319 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Bring back the fallback video mode selection in case both tries to read EDID info failed.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@39081 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Fixed strange/wrong indentation.
* Made sure the 80 character per line limit is honoured.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@38370 a95241bf-73f2-0310-859d-f6bbb57e9c96

Intel_extreme now centers the screen when one select a resolution smaller than the ne of the LVDS panel.
Also clean up the style and add some more TODOs.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@38363 a95241bf-73f2-0310-859d-f6bbb57e9c96

Always set the LVDS panel to its native mode, except for the 'display' part.
This allows to use lower resolution screen modes with black border.

Added a set of TODOs :
* The smaller scren is not centered, but aligned top-left
* The base resolution used is the one reported from edid 1.1, because I'm still not sure how to parse EDID 1.2. This resolution is too small on my laptop, but it works.

Also added two ways of setting 8-to-6 dithering for 18-bit LVDS panel. No visible result for me, unfortunately.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@38354 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Minor cleanup.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@38350 a95241bf-73f2-0310-859d-f6bbb57e9c96

Set the color depth for head B. This allows using 8,15, and 16-bit modes on lvds panels.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@38349 a95241bf-73f2-0310-859d-f6bbb57e9c96

Use the EDID info from LVDS panels :
* Read the EDID info on both port A (analog VGA monitor) and C (LVDS panel)
* If an LVDS panel is detected, report the EDID resolutions instead of the BIOs settings

This fixes #6326, likely #5096, and possibly some others intel_extreme problems. Please test.
On the other hand, this make the screen preflet show the full list of more reported by the LVDS panel. As we don't support
scaling, some of these modes are unuseable and lead to a garbled screen.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@38329 a95241bf-73f2-0310-859d-f6bbb57e9c96

* The DPMS code tried to enable the LVDS panel already if a digital display
was detected; however, it should only do so when there is an actual LVDS panel
detected.
* This should fix one part of ticket #3149 - looks like there are two different
issues. Thanks to Robert J. Gebis for providing me remote access to his
system.
* Minor debug output improvements.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@36941 a95241bf-73f2-0310-859d-f6bbb57e9c96

* added support for GM45 (might work for other chips in the G4 series)
* added header for dealing with binary numbers and bitmasks (C++ templates)
these "macro's" might not work well for long words, though


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33749 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Messed up the commit, sorry.
* Adrien? :-)


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33733 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Disabled the LVDS post2 for i965 cards, maybe that helps Adrien, and don't
break the display for others. If that doesn't work out, there is probably a
bit more to it.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33731 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Restored forcing the post2 PLL divisor for display B. This should fix all
remaining problems introduced with r33633.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33669 a95241bf-73f2-0310-859d-f6bbb57e9c96

axeld:
Restore ignoring the BIOS provided width and height in case the timings
suggest a bigger dimension. Also re-add the corresponding comment. Should
fix #4810 and might affect #4807 as well.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33652 a95241bf-73f2-0310-859d-f6bbb57e9c96

* The save_lvds_mode() function did not correctly support the i965 chipset -
I've now removed that code, and factored out a retrieve_current_mode()
function that can work on head A and B.
* This fixes Adrien's flickering problem on his laptop - I can't find the
bug ticket, though. Hopefully it does not break other laptop chips. Testing
would be welcome, as I don't have any other machine here.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33633 a95241bf-73f2-0310-859d-f6bbb57e9c96

* The panel display_mode::flags field was not correctly set, preventing direct
windows from working, for example.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33620 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Changed the way the device type is tested/set. There shouldn't be any functional
changes.
* Minor cleanup.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32353 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Make sure that the bytes per scanline is always a multiple of 64. This fixes
1680x1050 with 16 bit on i865+ (still need to check the restrictions of
older chips).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31277 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Fixed typo.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@28912 a95241bf-73f2-0310-859d-f6bbb57e9c96

OK, how completely can one mess up a single change? Fixed the intel_extreme
accelerant I broke.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@27499 a95241bf-73f2-0310-859d-f6bbb57e9c96

Fix the build of the intel_extreme.accelerant, I obviously compiled the wrong
target when I checked it. Move the target display_mode declaration back above
the check but remove the dereferencing assignment. If proposing the display
mode succeeds it also initializes target. Thanks luroh for noticing.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@27492 a95241bf-73f2-0310-859d-f6bbb57e9c96

CID 1039: Dereference mode only after checking it for NULL.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@27489 a95241bf-73f2-0310-859d-f6bbb57e9c96

Patch by Christopher Plymire, style-reworked by myself:
* first steps of supporting LVDS panels.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25975 a95241bf-73f2-0310-859d-f6bbb57e9c96

Work in progress (might not work for you yet):
* Now uses the AGP GART module for memory management. This greatly simplifies
the memory handling, and memory is now actually allocated on demand,
instead of a fixed size (stolen memory is not freed, though).
* The Intel GART module should now also work with older chipsets.
* No longer remove the GTT size from the stolen memory; this appears to have
been a mistake in the X driver. Not sure about the BIOS popup yet.
* The AGP module (in combination with the Intel GART module) is now mandatory
to use the Intel driver.
* Removed now superfluous settings (like memory size). Only enabling/disabling
the hardware cursor is still supported.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23781 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Simplified usage of the INTEL_TYPE_xxx constants.
* Added some defines needed when playing with the bridge controller.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23753 a95241bf-73f2-0310-859d-f6bbb57e9c96

Now clears the frame buffer before setting the mode; at least when testing,
one sometimes could still see previous contents of the screen during boot up
for some time.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23104 a95241bf-73f2-0310-859d-f6bbb57e9c96

The intel_extreme driver now finally works with the i965 chipset;
acceleration works fine, but overlay doesn't - that's next on my list.
Turns out the i965 differentiates between RGB-32 and RGB-32-alpha, and
didn't like trying to use the latter as display mode (the i865 didn't
care at all)... finding that took me *way* too long, though.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22780 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Now uses the new create_display_modes() function.
* Now supports the new B_GET_EDID_INFO hook under Haiku.
* Fixed build under BeOS.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22551 a95241bf-73f2-0310-859d-f6bbb57e9c96

Fixed PLL clock for i8xx chips again.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22415 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Fixed PLL timing computation for the i9xx chips - I mixed post2 min/max values, and did
not take the VCO limits into account; both could (and would during testing) create invalid
frequencies.
* Also reverted the order in which the PLL divisors are traversed to match the order of what
is used in the X driver to create comparable output (our error computation is based on float,
though, and should therefore create more accurate values).
* The i965 introduced a special register for the surface; the former display base register
is now only used for the view offset. Instead of setting the base manually here and there,
there is now a set_frame_buffer_base() function.
* The DPMS code will now also turn off/on the PLL clock generator.
* The code needs some more cleanup, and while the driver now produces the correct timing on
my i965 system, I'm now greeted by a black screen after startup.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22289 a95241bf-73f2-0310-859d-f6bbb57e9c96

Implemented I2C support to get the DDC EDID info from the monitor - it's working as is, but
nothing is done with the data yet (besides dumping them to the serial output).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22272 a95241bf-73f2-0310-859d-f6bbb57e9c96

* No longer switch between divisor register set 0 and 1; it doesn't really
make any sense.
* "pll" might have been set incorrectly on i8xx chips.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22253 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Work in progress to support the i965 chipset as well; still works on i865, but
doesn't work on i965 yet.
* B_GET_DISPLAY_MODE now returns the mode actually configured in the chip instead
of the last mode set; while this isn't really necessary, it allows to check what
mode was used during startup.



git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21321 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Replaced the 1400x900 modeline with the one from the nVidia driver - Stephan, does this
work for you, too? If not, just replace it with yours again.
* Added resolution 1680x1050 from nVidia driver.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19525 a95241bf-73f2-0310-859d-f6bbb57e9c96

* commented out span acceleration function, since it doesn't seem to work
* added mode for 1440x900, the numbers are just guessed, but work fine
with my monitor (after some fiddling), would be best to have some common
VGA communication code for all drivers to use and auto-detect the preferred
mode of the monitor
* messed around with the overlay brightness and contrast values to give
good looking video



git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19192 a95241bf-73f2-0310-859d-f6bbb57e9c96

Last set of minor fixes for GCC 4 build.
More will follow later, need to clean the fixes up a little :)



git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@18154 a95241bf-73f2-0310-859d-f6bbb57e9c96

wait_for_vblank() will now only wait 25ms at maximum (40Hz) - this is needed because
there is no VBlank interrupt when the display is turned off (and the code to turn it
on again actually calls wait_for_vblank()...).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17597 a95241bf-73f2-0310-859d-f6bbb57e9c96

* B_MOVE_DISPLAY and B_SET_INDEXED_COLORS should now work for the digital
output as well.
* Obviously got the register for INTEL_DISPLAY_B_DIGITAL_PORT wrong - it's
not 0x61000 but 0x61140, maybe that can explain the fun we had at BeGeistert :)
* Renamed the analog display registers to better fit the digital ones, ie.
replaced DISPLAY with DISPLAY_A - although this might be not really correct
as it seems that the pipes can be selected arbitrarily.
* Minor cleanup.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17566 a95241bf-73f2-0310-859d-f6bbb57e9c96

Some work to support output on the digital interface like laptop panels.
Need to clean this up, though. It even sort of worked on tic's IBM X40
on BeGeistert - if you weren't irritated by the fact some parts of the
screen were just black, that is :-)


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17565 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Now disables the VGA display mode explicetly, which allows it to work
without having a VESA mode set first (thanks to Stephan for noticing
this).
* intel_set_display_mode() now calls intel_propose_display_mode() to make
sure the mode passed in is valid. Note, B_PROPOSE_DISPLAY_MODE is still
not working correctly (which will cause problems for BWindowScreen and
friends).
* Minor cleanup.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17460 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Made the accelerant safer to use when cloned (though I didn't test cloning yet);
introduced a lock that is used in B_SET_DISPLAY_MODE etc.
* Correctly implemented B_ACQUIRE_ENGINE and B_RELEASE_ENGINE now (ie. they lock
the engine now).
* The lock of the ring buffers is now deleted when the (primary) accelerant is closed.
* Minor cleanup.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17453 a95241bf-73f2-0310-859d-f6bbb57e9c96

Now advertizes the capabilities of the screen modes correctly (ie. sets B_HARDWARE_CURSOR
and B_SUPPORTS_OVERLAYS).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17451 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Now allocates enough memory for virtual screens.
* Implemented untested B_MOVE_DISPLAY - note, the page_flip demo doesn't work
yet (didn't investigate yet, though).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17432 a95241bf-73f2-0310-859d-f6bbb57e9c96

Started implementing screen-to-screen blits, not yet tested.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17416 a95241bf-73f2-0310-859d-f6bbb57e9c96

B_SET_INDEXED_COLORS is now working correctly for B_CMAP8, IOW you can now use
8 bit modes with this driver as well.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17339 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Now using Thomas memory manager to manage the graphics memory; allocation
of graphics memory is now possible.
* Changed driver name to start with "intel_extreme" to have a nicer device
name.
* Renamed frame_buffer* stuff to graphics_memory* as the frame buffer just
happens to be located somewhere in the graphics memory.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17224 a95241bf-73f2-0310-859d-f6bbb57e9c96

Cleanup.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16879 a95241bf-73f2-0310-859d-f6bbb57e9c96

Now you can also select the refresh rate you like under R5. Looks like there is
room for improvements left in our screen preferences application, which ignores
the pixel clock values completely.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16876 a95241bf-73f2-0310-859d-f6bbb57e9c96

Added some debug output - the driver is actually working under R5 as well, I just
didn't test it correctly last time...


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16873 a95241bf-73f2-0310-859d-f6bbb57e9c96

Very basic driver for the "Intel Extreme Graphics 2" chips, only supports i865G for now.
Only mode switches do work, doesn't yet make sure the mode is valid, though.
At this point, this driver only works on Haiku, the R5 app_server is crashing for some
reason I need to investigate some day (maybe tomorrow :)).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16872 a95241bf-73f2-0310-859d-f6bbb57e9c96

The display line length constraint is different on <= G35 cards.
* Decide which constraint to use depending on the card model.
* May fix #8001, only tested on my hardware which already worked...

Add workaround for #8001.
* check known mode list first before sanitizing the target mode. However the optimal way is to fix the constraints in sanitize_display_mode.

Use timing constraints from the G35 programming manual (which are much more relaxed)

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@43235 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Add a couple more SandyBridge IDs. They might work, but I can't test them.
* Also add the definitions and some specifics for IronLake (ILK), but keep the
IDs disabled as at least the one version I can test with doesn't work yet.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@42869 a95241bf-73f2-0310-859d-f6bbb57e9c96

Style cleanups only, no functional change.
* Make the pointer style consistent accross all components, which should make it
easier when working all over the place.
* 80 char limits.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@42863 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Rework how registers are accessed. Most registers are now grouped into
register blocks and we encode their block into the register definition. On
register access these blocks are then translated into the final address.
* Set up the register blocks for (G)MCH and PCH variants.
* Remove most SandyBridge code that was actually PCH specific and is now taken
care of automatically.
* This will temporarily break SandyBridge support again until the right
transcoders are actually programmed.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@42857 a95241bf-73f2-0310-859d-f6bbb57e9c96

Add indexed color mode support for SandyBridge.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@42851 a95241bf-73f2-0310-859d-f6bbb57e9c96

Apply r42844 to the analog case as well.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@42845 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Use the actual (virtual) width and height instead of the display timing
values, as those might be slightly off (when coming from the GTF for example)
and cause needless display scaling.
* Tiny cleanup.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@42844 a95241bf-73f2-0310-859d-f6bbb57e9c96

Fix comparison.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@42843 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Add preliminary support for one SandyBridge mobile integrated graphics device
(the one in my new ThinkPad X1). The PLL is still off a bit so it has a few
blurry stripes, but EDID and mode setting basically works.
* Starting with IronLake the north/south bridge or (G)MCH/ICH setup was moved
into a platform control hub (PCH) which means that many registers previously
located in the GMCH are now in the PCH and have a new address.
* I'm committing this mostly because this way the additions are more easy to
follow. It is a bit messy and I'll clean it up more and possibly make it a
bit more generic. Also most of these changes actually apply to IronLake and up
and aren't SandyBridge specific, so a few of those additions will still get a
broader scope and new chips will be added.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@42839 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Implemented intel_propose_display_mode() using the new helper functions.
* In intel_set_display_mode(), we now use the sanitize_display_mode() method
directly in order to see if the mode is valid (it's valid when it doesn't
need to be altered anymore).
* This should be the final nail on ticket #7419.
* Automatic whitespace cleanup.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@42742 a95241bf-73f2-0310-859d-f6bbb57e9c96

Always set the palette registers even if the head is not connected. This will not do anything bad (if the display is disabled, it has no
effect), and since the test was a bit too constraining (I have an LVDS panel on head A), it would prevent setting colors for the CMAP modes.

This finally gets the \n demo working from the original binary from BeOS, without any change.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@42523 a95241bf-73f2-0310-859d-f6bbb57e9c96

* added support for the Atom IGD, based on the X driver sources (fixes #6202)
* fixes G4x PLL limits


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@40319 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Bring back the fallback video mode selection in case both tries to read EDID info failed.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@39081 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Fixed strange/wrong indentation.
* Made sure the 80 character per line limit is honoured.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@38370 a95241bf-73f2-0310-859d-f6bbb57e9c96

Intel_extreme now centers the screen when one select a resolution smaller than the ne of the LVDS panel.
Also clean up the style and add some more TODOs.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@38363 a95241bf-73f2-0310-859d-f6bbb57e9c96

Always set the LVDS panel to its native mode, except for the 'display' part.
This allows to use lower resolution screen modes with black border.

Added a set of TODOs :
* The smaller scren is not centered, but aligned top-left
* The base resolution used is the one reported from edid 1.1, because I'm still not sure how to parse EDID 1.2. This resolution is too small on my laptop, but it works.

Also added two ways of setting 8-to-6 dithering for 18-bit LVDS panel. No visible result for me, unfortunately.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@38354 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Minor cleanup.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@38350 a95241bf-73f2-0310-859d-f6bbb57e9c96

Set the color depth for head B. This allows using 8,15, and 16-bit modes on lvds panels.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@38349 a95241bf-73f2-0310-859d-f6bbb57e9c96

Use the EDID info from LVDS panels :
* Read the EDID info on both port A (analog VGA monitor) and C (LVDS panel)
* If an LVDS panel is detected, report the EDID resolutions instead of the BIOs settings

This fixes #6326, likely #5096, and possibly some others intel_extreme problems. Please test.
On the other hand, this make the screen preflet show the full list of more reported by the LVDS panel. As we don't support
scaling, some of these modes are unuseable and lead to a garbled screen.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@38329 a95241bf-73f2-0310-859d-f6bbb57e9c96

* The DPMS code tried to enable the LVDS panel already if a digital display
was detected; however, it should only do so when there is an actual LVDS panel
detected.
* This should fix one part of ticket #3149 - looks like there are two different
issues. Thanks to Robert J. Gebis for providing me remote access to his
system.
* Minor debug output improvements.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@36941 a95241bf-73f2-0310-859d-f6bbb57e9c96

* added support for GM45 (might work for other chips in the G4 series)
* added header for dealing with binary numbers and bitmasks (C++ templates)
these "macro's" might not work well for long words, though


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33749 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Messed up the commit, sorry.
* Adrien? :-)


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33733 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Disabled the LVDS post2 for i965 cards, maybe that helps Adrien, and don't
break the display for others. If that doesn't work out, there is probably a
bit more to it.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33731 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Restored forcing the post2 PLL divisor for display B. This should fix all
remaining problems introduced with r33633.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33669 a95241bf-73f2-0310-859d-f6bbb57e9c96

axeld:
Restore ignoring the BIOS provided width and height in case the timings
suggest a bigger dimension. Also re-add the corresponding comment. Should
fix #4810 and might affect #4807 as well.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33652 a95241bf-73f2-0310-859d-f6bbb57e9c96

* The save_lvds_mode() function did not correctly support the i965 chipset -
I've now removed that code, and factored out a retrieve_current_mode()
function that can work on head A and B.
* This fixes Adrien's flickering problem on his laptop - I can't find the
bug ticket, though. Hopefully it does not break other laptop chips. Testing
would be welcome, as I don't have any other machine here.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33633 a95241bf-73f2-0310-859d-f6bbb57e9c96

* The panel display_mode::flags field was not correctly set, preventing direct
windows from working, for example.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33620 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Changed the way the device type is tested/set. There shouldn't be any functional
changes.
* Minor cleanup.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32353 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Make sure that the bytes per scanline is always a multiple of 64. This fixes
1680x1050 with 16 bit on i865+ (still need to check the restrictions of
older chips).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31277 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Fixed typo.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@28912 a95241bf-73f2-0310-859d-f6bbb57e9c96

OK, how completely can one mess up a single change? Fixed the intel_extreme
accelerant I broke.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@27499 a95241bf-73f2-0310-859d-f6bbb57e9c96

Fix the build of the intel_extreme.accelerant, I obviously compiled the wrong
target when I checked it. Move the target display_mode declaration back above
the check but remove the dereferencing assignment. If proposing the display
mode succeeds it also initializes target. Thanks luroh for noticing.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@27492 a95241bf-73f2-0310-859d-f6bbb57e9c96

CID 1039: Dereference mode only after checking it for NULL.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@27489 a95241bf-73f2-0310-859d-f6bbb57e9c96

Patch by Christopher Plymire, style-reworked by myself:
* first steps of supporting LVDS panels.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25975 a95241bf-73f2-0310-859d-f6bbb57e9c96

Work in progress (might not work for you yet):
* Now uses the AGP GART module for memory management. This greatly simplifies
the memory handling, and memory is now actually allocated on demand,
instead of a fixed size (stolen memory is not freed, though).
* The Intel GART module should now also work with older chipsets.
* No longer remove the GTT size from the stolen memory; this appears to have
been a mistake in the X driver. Not sure about the BIOS popup yet.
* The AGP module (in combination with the Intel GART module) is now mandatory
to use the Intel driver.
* Removed now superfluous settings (like memory size). Only enabling/disabling
the hardware cursor is still supported.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23781 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Simplified usage of the INTEL_TYPE_xxx constants.
* Added some defines needed when playing with the bridge controller.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23753 a95241bf-73f2-0310-859d-f6bbb57e9c96

Now clears the frame buffer before setting the mode; at least when testing,
one sometimes could still see previous contents of the screen during boot up
for some time.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23104 a95241bf-73f2-0310-859d-f6bbb57e9c96

The intel_extreme driver now finally works with the i965 chipset;
acceleration works fine, but overlay doesn't - that's next on my list.
Turns out the i965 differentiates between RGB-32 and RGB-32-alpha, and
didn't like trying to use the latter as display mode (the i865 didn't
care at all)... finding that took me *way* too long, though.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22780 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Now uses the new create_display_modes() function.
* Now supports the new B_GET_EDID_INFO hook under Haiku.
* Fixed build under BeOS.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22551 a95241bf-73f2-0310-859d-f6bbb57e9c96

Fixed PLL clock for i8xx chips again.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22415 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Fixed PLL timing computation for the i9xx chips - I mixed post2 min/max values, and did
not take the VCO limits into account; both could (and would during testing) create invalid
frequencies.
* Also reverted the order in which the PLL divisors are traversed to match the order of what
is used in the X driver to create comparable output (our error computation is based on float,
though, and should therefore create more accurate values).
* The i965 introduced a special register for the surface; the former display base register
is now only used for the view offset. Instead of setting the base manually here and there,
there is now a set_frame_buffer_base() function.
* The DPMS code will now also turn off/on the PLL clock generator.
* The code needs some more cleanup, and while the driver now produces the correct timing on
my i965 system, I'm now greeted by a black screen after startup.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22289 a95241bf-73f2-0310-859d-f6bbb57e9c96

Implemented I2C support to get the DDC EDID info from the monitor - it's working as is, but
nothing is done with the data yet (besides dumping them to the serial output).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22272 a95241bf-73f2-0310-859d-f6bbb57e9c96

* No longer switch between divisor register set 0 and 1; it doesn't really
make any sense.
* "pll" might have been set incorrectly on i8xx chips.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22253 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Work in progress to support the i965 chipset as well; still works on i865, but
doesn't work on i965 yet.
* B_GET_DISPLAY_MODE now returns the mode actually configured in the chip instead
of the last mode set; while this isn't really necessary, it allows to check what
mode was used during startup.



git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21321 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Replaced the 1400x900 modeline with the one from the nVidia driver - Stephan, does this
work for you, too? If not, just replace it with yours again.
* Added resolution 1680x1050 from nVidia driver.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19525 a95241bf-73f2-0310-859d-f6bbb57e9c96

* commented out span acceleration function, since it doesn't seem to work
* added mode for 1440x900, the numbers are just guessed, but work fine
with my monitor (after some fiddling), would be best to have some common
VGA communication code for all drivers to use and auto-detect the preferred
mode of the monitor
* messed around with the overlay brightness and contrast values to give
good looking video



git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19192 a95241bf-73f2-0310-859d-f6bbb57e9c96

Last set of minor fixes for GCC 4 build.
More will follow later, need to clean the fixes up a little :)



git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@18154 a95241bf-73f2-0310-859d-f6bbb57e9c96

wait_for_vblank() will now only wait 25ms at maximum (40Hz) - this is needed because
there is no VBlank interrupt when the display is turned off (and the code to turn it
on again actually calls wait_for_vblank()...).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17597 a95241bf-73f2-0310-859d-f6bbb57e9c96

* B_MOVE_DISPLAY and B_SET_INDEXED_COLORS should now work for the digital
output as well.
* Obviously got the register for INTEL_DISPLAY_B_DIGITAL_PORT wrong - it's
not 0x61000 but 0x61140, maybe that can explain the fun we had at BeGeistert :)
* Renamed the analog display registers to better fit the digital ones, ie.
replaced DISPLAY with DISPLAY_A - although this might be not really correct
as it seems that the pipes can be selected arbitrarily.
* Minor cleanup.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17566 a95241bf-73f2-0310-859d-f6bbb57e9c96

Some work to support output on the digital interface like laptop panels.
Need to clean this up, though. It even sort of worked on tic's IBM X40
on BeGeistert - if you weren't irritated by the fact some parts of the
screen were just black, that is :-)


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17565 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Now disables the VGA display mode explicetly, which allows it to work
without having a VESA mode set first (thanks to Stephan for noticing
this).
* intel_set_display_mode() now calls intel_propose_display_mode() to make
sure the mode passed in is valid. Note, B_PROPOSE_DISPLAY_MODE is still
not working correctly (which will cause problems for BWindowScreen and
friends).
* Minor cleanup.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17460 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Made the accelerant safer to use when cloned (though I didn't test cloning yet);
introduced a lock that is used in B_SET_DISPLAY_MODE etc.
* Correctly implemented B_ACQUIRE_ENGINE and B_RELEASE_ENGINE now (ie. they lock
the engine now).
* The lock of the ring buffers is now deleted when the (primary) accelerant is closed.
* Minor cleanup.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17453 a95241bf-73f2-0310-859d-f6bbb57e9c96

Now advertizes the capabilities of the screen modes correctly (ie. sets B_HARDWARE_CURSOR
and B_SUPPORTS_OVERLAYS).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17451 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Now allocates enough memory for virtual screens.
* Implemented untested B_MOVE_DISPLAY - note, the page_flip demo doesn't work
yet (didn't investigate yet, though).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17432 a95241bf-73f2-0310-859d-f6bbb57e9c96

Started implementing screen-to-screen blits, not yet tested.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17416 a95241bf-73f2-0310-859d-f6bbb57e9c96

B_SET_INDEXED_COLORS is now working correctly for B_CMAP8, IOW you can now use
8 bit modes with this driver as well.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17339 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Now using Thomas memory manager to manage the graphics memory; allocation
of graphics memory is now possible.
* Changed driver name to start with "intel_extreme" to have a nicer device
name.
* Renamed frame_buffer* stuff to graphics_memory* as the frame buffer just
happens to be located somewhere in the graphics memory.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17224 a95241bf-73f2-0310-859d-f6bbb57e9c96

Cleanup.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16879 a95241bf-73f2-0310-859d-f6bbb57e9c96

Now you can also select the refresh rate you like under R5. Looks like there is
room for improvements left in our screen preferences application, which ignores
the pixel clock values completely.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16876 a95241bf-73f2-0310-859d-f6bbb57e9c96

Added some debug output - the driver is actually working under R5 as well, I just
didn't test it correctly last time...


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16873 a95241bf-73f2-0310-859d-f6bbb57e9c96

Very basic driver for the "Intel Extreme Graphics 2" chips, only supports i865G for now.
Only mode switches do work, doesn't yet make sure the mode is valid, though.
At this point, this driver only works on Haiku, the R5 app_server is crashing for some
reason I need to investigate some day (maybe tomorrow :)).
